welcome back guys this is a special livestream with Johnny guru the power supply expert of power supplies how're you doing man all right Brian nice to meet you meet you I guess a lot of people wondering arm so growing up as a kid I used to watch or read sorry a lot of Johnny guru reviews and arm I love the banter the humor that was the best part so you always just automatically sifted through the search results our Johnny go click click like yet is it a good power supply is it rubbish that was pretty much the verdict and what in your opinion makes or breaks a power spline what are the most important things so some of the things that people so the P the things that people assume is that efficiency if like it has made certain 80 plus certification is an automatic automatic means of quality right where really it's just efficiency some of the things you want to look at is actually what the temperature rating of the PSU is for example some of the cheaper units there they're only rated at like 25 C and it's never going to be 25 senior in your PC never might not even be in the room right well with that right with that the 25 so yeah it's a detrimental thing in itself because people with lower budgets generally buy cheap okay and yeah and the ones that come with the cases tend to be rated at 25 C now the importance of that is are the parts inside the power supply they have what's called a D rating curve right and so as the temperatures get hotter those parts capability to to output declines right yeah so that's one of the biggest things and then of course you know there's a lot of people say you know how long is this going to last if it's got these capacitors and you know we talked about this a little bit before and really the whole capacitor issue of my opinion is kind of overblown even the Japanese capacitors you get aren't actually made in Japan they're actually just Japanese bringing all because they cost so much to import into China so all the Japanese companies have factories in China now and that's how they saw the power supply companies but you know a lot of thing one thing that's really overlooked is the fan that's the first thing that's going to die in a power supply the Fei a fan yeah so it's really good to have a fan that I mean there's a lot of sleep bearing fans out there and unfortunately they don't last very long but you know it's like a good rifle bearing fan or an MDB fan or that bearing fan because that's going to be the first thing that dies ancestors buddies say because I deal with a lot of used parts and that is I've had to replace phantom power supplies and they generally you know they're dying to the like yeah it's yeah now oh it sucks those when it does die right and it just like completely dies and you don't know it then the PSU just heats up to the point where it's just dead it means those off you're done because all overheats and just dies because it's a that's another thing about a lot of power supplies they don't always all have the protection so yes right the over temperature protection over power protection short-circuit protection you kind of take for granted that power supply is going to have all that but they don't they don't always so with that though I did have some questions with regards to that no I've I don't know anywhere near as much as you know about power supplies that I did have a cut two power supplies now that would randomly cut out like it wasn't dangerous you didn't see any sparks flying on but when you like playing games or and they were rated way above what those parts would juice some of that power supply so I was wondering and you know ended up replacing the power supplies system would work perfectly other so would those would that be too many protections in place or what would that be y-yeah those laws just randomly cut out the machine like that well so really I mean it depends on the power supply and you know we don't necessary have to get in that but yeah but sometimes we'll see a power supply it'll just shut down like a cheaper power supply it'll shut down when you start up a game or benchmark that's a real heavy load because there's so much power is drawn by like the graphics card or even the CPU through just the one connector either a PCIe connector or the EPS connector you know for the CPU yeah and that power draw draws so much power so quickly that it causes a drop in voltage and then the power supply has under voltage protection it sees that the voltage is drop and it goes whoa something's wrong boom shuts off Wow so it's yeah yeah so if it's a unfortunately you know I see a lot of times with these guys that build systems for a living yeah you know they tell you you know I like this graphics card the CPU this much storage space as much memory they never tell you what PSU is in there right and then they put like you know 2g txt at 10 80s and they got a $40 power supply in there and they're complaining that the PC shuts down when they fire up you know just 3dmark right and it just shuts down oh they're complaining about this sudden incense in their realize that you know the smell of that beautiful smell in my room oh yeah so yeah it could be the under voltage protection and some power supplies have over current protection it's rarely that though that's that's when if too much current but its sustain current right so it's like it would have to be like 30 amps continuous draw and then it shuts down so it's probably not OCP but it's another like you said it's it could be any one of protections it could be just a cheap power supply or it could just be protections that are hyper sensitive right yeah and that includes OTP - like I said if the fan dies and there's OTP the PSU is going to shut down or if it's just a really hot environment I mean you know if it's thirty five forty five degrees inside your your PC and the power supply is just going to freak out and shut down well I do remember I used to have a C sonic power supply way back and that was blowing out really hot air and that did it for years and years and it never had a problem well so but that's a good thing though and that's it's kind of you kind of think that it shouldn't be blowing out hot air but what that's actually telling you is that it's it's doing its job evacuating the hot air out of the power supply if you are getting hot air out of the back of the power supply and you're juicing a lot that means it's just staying in the power supply right you know so that's and a more efficient I mean the thing is is you know that when a CES converted to DC obviously the byproducts heat yeah so the more efficient power supply the the less heat it's going to produce right so it's not like effect if you have to plant and power supplies one's not going to run hotter than the other yeah but if you feel that one of them has hot air coming out of the bag or hotter air coming out of the back than the other that just means it's moving that air better so I have a question though with this fourth regards to this um we are you know you've got different bowel supplies designs now old-school used to have the fans sort of pushing air in that push sort of just push now oh the ones with the Ferrand and yeah yeah so and there you've got the fan yelling it up which in your opinions battle well obviously pushing the air through is more efficient but it's those 80 millimeter fans are loud yeah and and and quiet is like you know so important for people is that more now more than ever everybody wants quieter and quieter you know water cooling is actually making a comeback before you know is like because it was cool and now it's because it's you know it's quiet right you know um so do you think we'll ever see a water-cooled pass fly I have already seen actually yeah I've already seen 10 a bunch of water-cooled power supplies that you know ten years ago coolants made a really cool water cool power supply had my machine it was it was basically a mineral oil bath the PSU was all sealed a little bath and and I think bits powers partnered up with FSB and they have water blocks on on an FSP power supply right now yeah so yeah I mean it's kind of a that's kind of a weird thing because power supplies don't get hot enough really to justify having to water cool I mean like if you look at some of the Corsair power supplies with the zero rpm mode yeah I have people freaked out all the time it's like oh my god the fan never turns on I'm like you know what do you got well I've got you know I've got like you know one 1060 card and I bought a thousand watt power supply I'm like that person that thing is never gonna turn on it doesn't matter what you do yeah it's never going to turn on because that power supply is never going to get hot enough to justify using a fan plus the efficiencies right out there oh yeah that's what saying yeah so like I said if you had you know this the two two power supplies of the same efficiency one is not going to be hotter than the other because that AC is going to get converted to DC and that yeah that efficiency difference that's your heat yeah that's about everybody that's how I'm going to dance yeah I'm from your articles yes but a lot of the time too when I when I look at the power side like I've I use a in Japan bar when I was in I was hunting for used parts I'd use a lot of like a delta ref ESPYs these guys in Japan they'll selling these things so cheap and they didn't know their value and their 500 watt power is getting the used ones and you can't really get those deals in Australia or us all because I don't notice I've looked for them a lot and I can't find it but in Japan dime a dozen and so a lot of people be like using a $10 pass but its garbage is like laughs its adult yeah yeah yeah I mean if you got a brand name I mean the reputable tier one brand um you know yeah you're fine as well as I was trying to explain like guys this is going into service right yes not good yeah that's a thing if it's a server if it's server power supplies are you know mission-critical right yeah they're made to not fail they don't necessarily always have the best voltage regulation or minimal ripple that's all that's all consumer level product because consumers read reviews and and it's like you know this guy makes a great power supply now the next company comes will and they have to make it better so they can get a better review and and so we see power supply's leapfrogging themselves every years for its performance the servers it's just it's all about efficiency and longevity yeah and that's it but with that said what can get better on past laws I mean we're not talking RGB lighting yeah so a term that gets used a lot on Johnny grew calm is a sorry I'm tired mythic yeah performance because we're to the point now where it just our voltage regulation and our ripple is so um sticking so mythic there we go we use that word again yeah that it doesn't matter anymore right so now people and we're seeing it this year right they're looking for little niche things to do with their power supplies to make them different RGB lighting yeah water-cooled yeah yeah stuff like that so the ripples basically gotten to the stage where can it get a lot better or it's so I mean so the thing is right now it's it's so tight I mean when you're done a twenty millivolts yeah you can't differentiate if that's coming from the power supply or if that's just line noise you know it's so yeah it's just so anything that's twenty millivolts are better it's it's a blurred line right so and so that is that that's also a critical factor in in getting the extra overclass like you've got people - well yeah because I say for instance I've seen other people review products and they're like this motherboard got an extra 100 or 50 megahertz and then they've used a different house blather yeah yeah and I've known in that the better yeah yeah impression what not the better the the voice of that side of that line better idea and so that helps with overclocks exactly no it does it really does that and and not to brag but that's that's why a lot of the guys like using the ax 1500 I mean I know that sounds like a plug but um no it's when they don't look at that when the power supply is not sponsored right and and and the overclocker brings their own it tends to be the ax 1500 i there's the is it's digital and if the ripples just so you know so divide yeah clean so you design which power supplies at corsair did you desire help design or oh let's talk about those well we got to know this so i want to know so the ax 1500 was your no actually no x 1500 i was that was a very that's be that was beyond me i mean because that was like the first digital power supply if you told me that you could replace all the analog ICS and power supply with a bunch of microcontrollers I would say that sounds absolutely nuts billion but the engineers of course here pulled that off I actually came in after that so you know stuff like the SF series I was part of that team and and of course the you know the HX and the TX am everything that you've seen launched in the last couple years and and then of course you know I always have to go back because I'm like oh man I found you know found this mistake this problems that back refresh the product so that's why we always you always see us with new product every year there's a reason for that because we're trying to try to be everything to everybody and make everybody happy so if somebody has one little nitpicky complaint in a review and a lot of people say well that's just nitpicky it's my job to go back and fix it for the next time around but that's that's the thing yeah and that's what I like about Corsair guys I've spoken to him about little things that I didn't like for instance the 460 X I didn't really build some things I didn't like about the case right and I've listened to those fair that re refreshing that and making things better so they listen and they really yeah that's the cool thing about the environment yeah of course air you know we've got all the different product managers they have their own specific product they own they own that product right so if they get feedback they have you know they have to they have to follow up right because it's like that's their job their job is like okay this is my baby now you're insulting my baby yeah yeah you know so is that you know you can't have a big ego right because you have to be able to say crap you're right I gotta fix this great you know whatever you places coolers power supplies whatever you know you have to have an attitude that's a positive everybody makes me yes oh no I make it better people watching me for a long time now how many mistakes I think I make mistake every single day of my life but people did I get a guy's in the comments you are a mistake Brian okay okay there's gonna be too far but uh so we had some questions yes it's um which suit is a best for an old net I say sue is that one I just that's real casual Australian in me what is it sue instead of PSU oh dude that's cool but I do know that Australians like to abbreviate everything for breakfast sunny after sunglasses yeah so I should get used to that okay sue got it is away if we have it here so which sue is best all-round or not say which bought for a budget right I guess a lot of people buying a GTX 1060 are x5a and of course you know where we are five six I could tell you to buy the most expensive Corsair power supply and I wouldn't that would buy but the thing is and it and the design of the sales figures show that the rmx has been the proven most size got very low very low failure rate yeah it's only gold efficiency but like I said it's you know you're talking two percent difference and it has a zero rpm oh that works really well because it actually uses a microcontroller Corsairs like I believe the only company that makes desktop power supplies that uses a microcontroller for the fan speeds well so we can actually program the fan profile in there what what RPM to start at how to ramp up and stuff like that so our MX is our least expensive unit that uses the MCU for the fan controller fully modular of course and now we have the individually sleeve cables that we sell separately you can customize the colors and now we're shipping it in white I'm sure you saw that the sweet white ones and it comes with the white cables too because the demand for that was just so high we did a limited edition of the RMI the arm 1000 I yeah and they were all gone like in under a day one and and then everybody was just like oh my gosh I got to have this thing so we did the rmx because it's more mainstream so yeah so I would say you know overall just the big best bang for the buck I would say is the rmx have the coolest a lawn yeah okay yeah I use an arm i but that's because I'm kind of geeky about wanting to monitor power consumption voltages and that is that is a good thing with the digital link via USB - yeah yeah I had I've got that's the problem at the moment I'm having about three digital Corsair products but only two USB headers yeah yeah so I got to figure out which one to hook up so yeah look at the the lighting the light yeah the RGB lighting a cooler and then the power supply what I ended up having to do I got a piece a USB card yeah plug everything for that yeah we do have to address one things a lot of my viewers talk about the vs series yeah we have to talk about the V Series now I get a lot of people who they say it's crap I've used the vs pounce blog had no problem yeah the s550 is that it's a budget entry-level battle supply yeah and for me it's always done the job I use two of them now and yet it builds yeah I mean so you can you can say it's crap because it is the least expensive corsair power supply you can yet you can buy but we do have to maintain a standard I mean you see there are a lot of power supplies out there that aren't even 80-plus certified it might not even have active PFC yeah because it's not required in every country yeah um might not even it's not required in this and it's not required in Australia or the US right and it's a you know in so yeah it's I mean it's the least expensive it's totally no-frills um but it works you know it totally works yeah it's not modular it's only a sleeve bearing fan only has a three year warranty you know there's reasons for these things but you know if you got to hit a certain price point then you know there it is well yeah I mean I'm especially consider 500 future watts is actually a lot of power it is yeah it's getting way overkill I mean unless you're running SLI you most people die anyway and if you're running that 550 watts of power arguably you'd have expensive gear you wouldn't want to put a via Skype to show on there anyway so that was my argument for me is like okay you're putting this with a 1060 or 580 and a mid-range CPU and that generally those configurations will juice maybe 250 Watts when you're gaming right so it's like that's well under the 550 watt power supply is going to be sitting there yeah and that's why that's why I like like the RMI series for example is because you can actually get rot you know actual data numbers that what would you know what you're actually power consumption is because even though you can't see the link screen if you're running benchmarks and stuff it does have the login capability if you turn that on and then it creates a spreadsheet for you okay and then you can pull the spreadsheet out and see what your parish consumption was while you were benchmarking and stuff like well so I noticed some I noticed lately I've been mafia 3 has been breaking the the exact Crysis 3 was the game that stressed the whole system at the most at once and then yeah sure enough mafia 3 is now the king for me like family effort for me I think the latest one I found was a major power suck with Witcher 3 which is 3 oh yeah but I'll have to try mafia yeah definitely try mafia so I think that's the way to do it but we've got some questions arm yeah so we got I think someone wants a how do you measure ripple yeah you need oscilloscope you need expensive gear and well the oscilloscope doesn't necessarily have to be expensive but you'd have to measure it with a static load otherwise it's just going to jump all over the place oh yeah you would need like a load tester which is expensive that's the expensive person okay now one more question I have is it better to be under the voltage rating or over it doesn't matter so like throughout 11.9 versus 12.1 doesn't matter because so what it is what you want to look for is how much the differentiation is from the low low to a high load so if you're always under 12 volt but let's say your drop is like eleven point eight to eleven point seven nine yeah I'd rather have that than a drop from twelve point three to twelve point two right yeah I don't care if it's above or below it because the thing is is you're feeding that power is going to power regulators on the motherboard the graphics card it's going to it's got a wide range capability to convert that power down to what it needs to be alright so it's okay to feed it power with the plus/minus of like five percent but the thing is is you want to make sure that that power is stable because as that power fluctuates it takes those it takes us FETs awhile to you know to cycle the voltage where it needs to be you know let me call it a bad analogy who's going like the throttle if it's not stable kind of thing the Kazi yeah that's all kind of yeah you want a nice light nice and smooth right you know and and that's what you want you don't want the sudden you know spikes and drops and stuff because that's going to hurt your components down the line so what if you over Volvo severely say you are like 12.7 or what I have seen it before now a bad bounce fly about twelve point seven on this woven yeah it's that high that's not good because like I said so you've got you've got you know those components you're feeding power to they have a tolerance yeah right that's why the Intel spec says you need to be plus minus 5 percent so 11 point 6 volts to 12 point 4 volts is where you want to be okay no less no more um and so yeah so if it's too high or too low the reason why Intel defines that is because they know if you're too high or too low that's going to stress those components they they're going to freak out because they're like wow you know it's this more voltage or less voltage than I can handle and screws everything out so you'll be making pop culture that's yeah amongst your friends in detection yeah we got some questions someone else about EVGA b3 is that I don't know just asked they said ask him about the EVGA b3 died it's based off the super flower lead x2 sounds good so I had a super cell pretty good and so yeah this above there's a lot of good pounce flies out oh yeah yeah yeah yeah when it comes down to a lot of times is you know what kind of support you know if it's a brand name I mean I put that out there too cuz I especially like in Europe and there's some like totally random brands I've never even heard of the Apple they just so yeah cuz I seem in the forms right it's like you know hey I got this you know Butch Cassidy brand power supply what do you think of I'm like Oh what did I did here I mostly if it's a brand name it's like you you want to you know do they have good support do they have good warranty yeah if you if you do get a 10 year warranty or do you get a 1 year warranty that you have to register oops I didn't realize I forgot to register and I don't have a 10 year old fashioned and then they let it land and they're allowed to advertise ten you want yeah yeah so that's that's the kind of thing that people need to look for when it comes down to you know the bottom line and also some you know support if you have problems like you know some of they can help you troubleshoot if you're having any show arm you know that it did you know do they even have support they have a phone number and you know stuff like that's true as well so I've had it yeah I had a young you get probably gonna hate on me for this but I I am because I deal with a lot of used power supplies i spliced in wires and instead of fighting those modules connected oh yeah so I wouldn't have the gear at the time to actually measure the voltage and great I was in a rush and I'm like okay I'd be splicing off the 24 pin to get the solder connections and very very odd but it did work I never have as it it's a and it did work and it was very odd but also on that note I did make my own troubleshooted my own extra CPU connector modular and took it from a PCIe connection rewired it made it a CD a reverse that yeah and in reap made a CPU connection so I've never had problems with hacking power supplies but a lot of people don't even going to electrocute myself but what's the best way to when you're dealing with power supplies what's the best way to if you have to work on them what would be the best way I've always the DC is not going to hurt you right so I mean the only thing that's going to really hurt you in the power supply is that bulk capacitor inside and so I mean just don't don't you don't open it yeah I don't know because you if that thing is charged up and you open it up and you touch those contacts on it you're dead it's 404 what well it depends for 20 volt 440 volt and I that you don't want mess with that but and there has been people that have gotten killed as I seen it is there's a you to be of dude like going to shooting back off where yeah you know what I mess with that but the DC voltage now you'd be lucky if you even felt a tingle okay so basically just going to the wire but to drain a power supply probably I've always just turned it off from the wall and then actually press the power button yeah so you know yeah the best thing to do you know and it's it's you know a lot of times and this might be good information yet for your viewers when you when you turn off your PC and even if you flip the switch on the back or even unplug it right and you'll see that the LED is still on on your motherboard yeah okay that's just because the power supply still charged up and then that led if if you don't have much of a load on there that led can stay lit for like 15 20 minutes I've seen it yeah long time just sitting here like yeah well one times I fast afford it was like a good three minutes yeah and because they had multiple LEDs yes staying on so everybody freaking I was like oh my god there's something wrong with my motherboard no no it's the the power spies doing what supposed to do it's it's thick because the capacitor that you want that capacitor stay charged because if your power goes out yeah the PSU it can actually keep running to the power comes back on now we're not talking like a blackout but like if your power dips or something like that when AC turns on in some old house and the voltage goes down and stuff up so yes you would keep the vacuum yeah with the vacuum cleaner I remember yeah back and cleaner air compress or anything yeah with a motor yeah and when I was a kid I had my cheap cheap computer mum would turn on the vacuum computer back and clean in the end their whole computer to turn off right and so that that's hold up that's what hold up times four that's the whole thing about hold up time and that hold of time that the whole definition of the hold of time is how much power can that that big cap in the parents buy the bulk cap we call it can hold a charge but that I like going back to it it could also kill you I yeah it has it's I guess it's a double-edged sword right is if it's too much it can is the inrush current it can no no no no it doesn't affect well it it can't affect the inrush current because if you have no AC power going to the power supply and you flip the switch on it or surge protector yeah then then that's going to cause a rush of current to charge that cap right yeah so that in itself could cause a problem it's really rare though and if that causes a problem because there should be the proper circuitry in the parish play to prevent that from being a problem but to go back to yeah so what you want to do is I mean like I said II you can you can have that PSU turned on and plugged into a motherboard for you know however many minutes and that cap will still be charged so the best thing to do is just have a some kind of load on there fan a hard drive you know something to just drain that down yeah yeah just just have a fan on like I've never thought of that yeah just touch it and until it sits until it's completely drained house plus they're dangerous things guys don't know what don't do what I do if you ever seen my used budget builds don't do what I do I'd be like Dre I drained the powers wide open up not spray parts cleaner on it clean it all down get all the dust off yeah thing would work like brand new sure and people tell me I want electric humor so I was like as long as it's not charged how do you make sure the powers players got not a single bit of current in there so I mean if we talk about an LED being lit for three hours and three minutes sorry no 15 minutes like that that's enough charged yeah yeah kill a human being so yeah yeah because the charge runs through your button have you uh what's the worst story you've heard about it from a guy in China I mean got shocked and died he was he opened up his power supply and I think but he was really dumb about it though I think I'm still plugged in as with the story Wow so he probably got it from both you know the the from the wall the cap everyday you know he just completely messed up but that is a that's a pretty weird one but yeah but that it'll throw it at the very least it'll throw your back yeah so do not open up your power supply's guys unless you seriously know what you're doing so like or you just you know there's you really know that it's at what you really have to open up a power you should well in early it's either dead or you want it yeah if it's out of warranty and the fan dies right you want to replace the fan yeah you know and and a lot of the really techie guys though they'll do like full cap replacements on Wow so what's the with the cap sorry we don't have V s550 with the caps right you ran that thing 24/7 saved for instance on a 300 watt load as a gamer would on a vs 550 how long would it take for those caps to get bigger and blow up what would be the average outlook I believe that's that's kind of it so we do a cap life analysis on all the power supplies that's pretty much how we determine our warranty should be at because there's a formula that you can use based on data that you get from the capacitor manufacturer that says if you're running at this temperature 24/7 you know with this load or whatever this is how long that caps going to last I can write so so I did the easy answer for V S series is going to be three years threes okay it running 20 volts 24/7 full load yeah yeah and that's I that's that's we have to determine it 24/7 folow because we don't know what people are going to do with our power supplies well and if guys if you're playing on you can be to 24 hours a day doing something and wrong like I win the lottery and that's like all you have to do now is just play the games all day don't do a guy eight hours a day max and even that's pushing it when I was young I did the big session sixteen Isles and World of Warcraft oh did you play what Walker no no I sought to Warcraft to I couldn't get into the dough yeah I'm glad I'm glad to hear that but that game I'm more of a s guy yes what games do you play like I'm talking about the ocean over watches the big one right now yeah yeah so what what character do you play I just go all over him yeah yeah I mean I'm I like junk rat yeah he's my favorite at the moment I play a bit junk rat and you just run around cuz he kind of let you get into places that people camp and like do their little Snipes and stuff and you can kind of get in there without being seen yeah I'm looking for the quick champions from finally like I was on the beta but I could never get on the darn server it's like oh yeah here here's the beta program downloading i'm like i coul fired up and say sorry can't give it server has it okay and so what about gila what does Johnny Gerber use in terms of monitor grab his car BP you my monitors are actually pretty I've got the I've got the Samsung 120 Hertz uh 20 what does a 20 24 I got three of those oh yeah boom hundred twenty huts so you like the difference between 60 going up from 68 yeah you can I think I think a lot of gamers like people who play PC games can tell I can tell ya and I've tried the 240 Hertz recently yeah that was crazy that was really crazy was actually really not yeah so one of these days I want to get like a curve monitor those I don't want to end to Samsung to see if SCIM nah I'm not gonna do it my viewers know I talked about the Samsung not too much but I do want although I did see that Dell a K yeah yeah but do you think though I think wouldn't monitors Emma I think we cross it is okay so but what about monitors though how some of them have their power supplies built-in they don't only juice such little amount yeah they don't they don't pull much power so what's the usual bit like minima so my Samsung's they all have the internal power supply okay you get plugged the power so it can be I hate the power pricks sitting all over the floor but you know you know funny thing with monitors I find the actual display outs die before the Pat light if a power locally and why don't you know would you know why the display ports which is done I like it's really it's bizarre to me because like I'd have a DVI port blow out on the model and the HDMI works so it's still ok but yeah I'm no idea I mean I just you know what I do have some idea because if I apply some of the power supply knowledge and get to that I mean there's things like like when you have surface mount components we run into this a lot with power supplies yeah if they're mounted on both sides of the PCB yeah right and you float it through the wave solder but then you have to put it in a jig and get it to assemble the rest of the way you can actually crack the components on the bottom but you don't crack them so it's a complete failure it's like it's like an intermittent failure or it's going to fail in a matter of time and when you look at it under a microscope after you take it apart and you'll see that just that connection of a resistor or dye it could be anything it's it's severed so could that be where that oven fix could fix it or not usually salt you actually really sold a broken joins properly well no actually uh so Jeremy is joining her he he he does a lot of Bitcoin mining okay and he's always frying graphics cards but he just no he just throws them in the oven heats him up yeah resolder in the oven huh just in kitchen oven yeah pulls him on they work Wow so it's like all right man whatever but he's actually he's done it before was I yeah I mean I don't know the technique properly I just shove it in the oven and I've seen one time I saw okay you know that you're the trad Orange I'm like this is good too I come to the bit yeah yeah but it does worry not all the time but it does we're so so if it's dead it's worth a shot right cuz what do you want to make a worse what do you have to lose I mean I guess if the silicon's did which is a difference yeah yeah if you walk the silicon but you know what I mean I have to tell you what the likelihood of the actual silicon parts dying same with a power supply right yeah is so rare I mean when I see power supply failures it's typically just parts that just yeah what do you think they come apart you know they did come off the PCB they did separate from the PCB and stuff like that or they sure to another part because they were not correctly you know oriented or whatever because you know it's not a fully automated process to make these things yeah but you know you do have they call the pick-and-place machine it puts all small parts in there and I have to go to that wave solder and you know you try to make sure you have a jig that holds everything in place but it's not a perfect process so what would be the kid worst conditions versus the best conditions like we're talking about humidity maybe or a drier environment be worse for cracking things I mean I don't know these I just guess to make that a more humid environment will actually probably be better for your parts yeah now I don't you know I don't think humidity well so there there are humidity ranges and you know and it's so like if you go through one of our technical documents you know they're internal but I'm just saying if you did there's a thing for you know altitude requirement temperature humidity you know and stuff like that so as long as you're within those parameters actually none of them have an effect it really the thing is is was it built right in the first place in the first place that's all it comes down to projections like the coating on the piece no I mean I know I mean actually you know the process of actually building another design I mean obviously the design is huge right you can slap together you know the cheapest power supply in the world yeah you know and and then and then build it perfectly but it's still a cheap crappy power supply but I'm just saying even if you have a fantastic power supply yeah and one thing goes wrong during the assembly process yeah you know three months six months one year down the road something can sell me something to fail because like I said you can have just like a tiny little break in the solder yeah and you know gone and then of course if you live near the ocean and you leave your window oh god yeah no I used to live in Florida exactly back in the day when you know you'd have a dim and it had the the the gold contacts and the tin in the slot and then the the corrosion would literally well the memory into the motherboard and it's just like oh my god you know you can't even get the thing out there you just seem a line of rust lovely brutal is hard this is the one more question I was going to go but I had a brain flop so I completely forgot but we can go to the viewers for some questions on the time refresh so if you guys have any questions for Johnny guru then be sure to ask them I mean a lot of these guys let's solve the use parts as well and parts of course but what's the most actually because we're talking about the 290x or the the GTX 480 what was the most single power-hungry card out there because I think the 290x comes pretty close yeah it's your boy Eddie a GTX 480 was pretty yeah 295x2 yeah that's uh what uh what's the most power hungry gravis car you know what it's funny so I actually built a machine back in the day God must man well to give you an idea I would have to say probably 8800 GT X I mean I know that's going way back but I am i work for BFG yeah and I built a machine with the sole purpose of consuming as much power as possible so I had the you remember the AMD bulldozer no wait what does it called via not the bulldozer shape all job I don't know as a dual dual dual CPU board yet with two gtx to to a 8800 GT X's yeah and I'd run benchmarks on that thing and believe it or not I would pull a thousand watts from the wall Wow yeah it was crazy let's you I've actually never seen a thousand watts from the wall yeah is crazy so it also get one more point let the Bitcoin miners though they do it oh yeah now with the the value of the Bitcoin going up I am seeing high-power power supplies flying out the door because like the asic miners um you know they used to be people use a six miners because they're more efficient than graphics cards a bla bla bla but now you have a six miners that use 1600 watts for one a six minor right so they've gone through the roof Wow so remember the Lokpal but they were low-power and now the ones they're using now to really mine art is you know 1667 watch for the one minor so I hit people so people mining other cryptocurrencies now with the graphics cards yes yeah because you can do yeah so like I was saying about Jeremy and throwing his graphics card in the ovens he does altcoin because he can use the graphics cards it doesn't pay for power so so he runs into the coal ser office no no yeah he lives okay yeah but yeah so he although we did do that one um yeah um so yeah he does all coin and yet and he uses graphic squares for that and he just recycles and you know so one thing I am curious about there with power supplies is there many people who do DIY like they get all the components and build the powers now that it knows yes Cooper could you is there is there something like for instance with a chipset you of course you got something holding you back like a multiple but with say for instance a power supply would there be things out if you could get all the parts you can do and because so the most like something like a motherboard you have like a four layer six layer board there's traces in between stuff like that obviously a home person can't build that right yeah but a PSU PCB is typically only it's either single site or double site at the most yeah right at the most it's double sided so yeah it's theoretically you could do if you could if you could print if you could print a PCB for it and make sure you get all the right components yeah you could do it yeah but it's it's the thing is it's more time and money than it's worth because yeah it had Naposki so much darn money we'll have same people building there are in keyboards and I'm that's my initial reaction well that'd be a big waste of time yes sir yeah no I think it would be cooler to just like mod you know Marta Parish play like you know instead of K so we'll do that like not not so much it's funny to actually I would think that is fairly you know that would be fairly common practice I mean I see people the paint and the stuff right but you know cut a hole on the side put a window in it or even you know like we're talking about the the water-cooled ones before open it up you know take the fan out put water block of water blocks on top of the heatsink you know do a bunch of holes in the in the housing for for additional airflow and yeah say hey look I just made a water-cooled power supply here's a very specific question so I'm like we're gonna look through questions guys sorry if I miss any we've just got I'm on a laptop monitor so we've literally got like a little screen for the stream it is pretty it is pretty tiny but this it has been really good laptop so is it looks like a very specific question I asked him about ask Johnny oh my god out matter about module this fixed cables in voltage variation or efficiency is that as a good that is a good question yeah so yeah so obviously any point of connection is going to be an efficiency drone right an efficiency drop you know because you have that it's it's a it adds resistance right in the pins you know everybody's like oh you know the gauge of the wire you know the number of connectors the pins are the the part that's actually the most susceptible to high current right yeah so when people do things like and it just drives me up the wall they use adaptors like like a like a molex to a SATA adapter or something like that yeah they're they're putting stress on those pins I you know it doesn't matter what the gauge of the wire is or that you've made it like 50 feet long I don't care yeah you're stressing the pins out so on a modular power supply then that's like 10 times worse right because you have the pins where the cable plugs into the modular interface and they'll so that's the point of where the most pals going yeah yeah because everything that's plugged into that cable yeah has to go through that connector yeah right so you know I I had a guy just last week asked me he's like you know how many how many hard drives platter drives can i plug in you know can I do seven and I was like how many how many connectors are on that the cable now and he's like four I'm like then four you know because because you don't want to overload right and with the pattern I can't speak for other companies but we like Corsair for example we choose the gauge of the wire depending on how many connectors are on there too so if we only have like a couple connectors on there we can get away with like an 18 gauge wire but if we have like four or five connectors 16 gauge I'm sorry going backwards Nelson yeah 14 H is a smaller number big one so yeah so so the thing is so you don't want to screw with that engineering and say I'm going to start adding connectors to is now you've just completely thrown that that out the door cuz in a way I've been a fan of semi modulars you gotta have to have your twin yeah you gotta have a 24 pen in the eight pin anyway yeah and so I've been it so do you think there's one of the semi modular designs are kind of like the bad I guess but the of both worlds like for the perfectionist yeah yeah well I mean is like obviously I mean it goes without saying that that's going to be less problematic than fully modular right and fully modular is going to be worst-case scenario because the potential connectors to go lose that can be the potential for the pins to fail what I was talking about before and obviously semi modular you don't you won't have that problem okay at least with the 24 pin in the EPS yeah right I do like fully modular though because you know if I'm changing things on my PC a just click lick lick lick lick just pull them all out and then my Paris plays just a box it is giving far so yeah so that's true okay we'll go to the next question so we got here so okay ask Johnny if there any problems with wine with the RM 1000 I you know what actually in this day and age every power supply is susceptible to coil wine because they have to have the to get the better efficiency they have to lower the switching frequency down to almost audible level right and so if those parts that are wound whether it be a coil or transformer or even a poly capacitor get the plastic if if they're not made absolutely perfect this goes back to where I'm saying which is like perfection is impossible so you never know what's going to happen down at the end of the line we're not never but I mean you hope that everything goes perfectly that you know then you end up with these vibrations yeah and those vibrations cause audible noise yeah and so you know at in the engineering department you know we go when we attack and we're like all right cool everything's perfect and then six months down the road something happens because the capacitor manufacturer the coil manufacturers well dad they hired a new guy and he did something wrong you know or he didn't put enough you know the the lacquer on the on the on the closure so I'm like that and then boom all the sudden somebody's complaining about coil whine yeah you know that is a shift funny thing with design sort of changing it's not your fault like as yeah I mean back in the day you could have really high switching frequencies that's why old pitches leave earlier you know Henrik's patters play from 20 years ago never made a noise I'm like yeah but the efficiency was like semi percent you know of the switching frequency so high if it was making noise you could have the you know the crappiest parts in there you wouldn't hear it you know so it's just you know it's just technology getting ahead of itself you know so we'll stop finishing up the Q&A what are some this is I like this question what are some good rules of thumb when you're buying a used palace floor you just buying a power supply what's um just a general I mean my would be stick to the solid reputable brand especially with a power supply there's no room for is one of that is the one component that if you have problems the potential from a lot more grain right yeah exactly so definitely don't get don't get something that nobody's ever heard of you know you can't find a review for it there's a reason for that is because the company that made it never sent any units out for review and and then and then the thing is like I said the fan type if you if you want to make sure if you don't want to have to take the thing apart and replace the fan right yeah if you know that it has like a ball bearing fan or an FTD fan or some like that yeah like you know going back to what we started with the the fan is going to be the first thing that fails in power supply so if it's a good fan then you know that you're going to get some mileage out that power supply even if it's used see you behind in hosed yeah yeah unfortunately though you can't tell things if you're buying to use you can't tell how hot the guy made it so that's the thing because you know like if you run it if you run a power supply and extreme temperatures those caps are going to bulge and but that's another thing too is you take a flashlight shine it in the grille have a look you can you can tell when because you know they have the vent cuts in them and they'll split right and you might see a little bit of electric lytic you know coming out of top something so if you see that then it's like much no don't don't buy that one unless you know how to replace yeah because that would be that would be because of high temperatures because if the power supply is not that old and the fan still works but the capacitors are bulging somebody ran that thing way too hot yeah and so with that though with that what's say for instance we got a missile be my last question with a refurb with a refurb alright when it's something fails how likely is something else going to be near failure because of that original failure say captain blow is obviously is that that's a good quite so that's and that's a dangerous thing too because so if you if you have a cap that's that's completely bulged out but but the power supply still works right and you don't know it okay then that's causing things down the line to not run correctly the ripple could be like five times what it should be and stuff like that and that's when you end up with power supplies that kill other parts yeah and you're sitting there freaking out going what's going on it powers and that's the thing that bugs me about power supplies is that people assume it runs works yeah but the thing is it's like it runs and you could have just killed your last three motherboards like I can't figure out what's going on I'll just keep replacing my motherboard hey maybe it's your power supply it's killing everything I used to do tech support used to be a manager in RM a department yeah and we have people too I mean the whole reason I started joining guru.com was I was in an army department for Annie Taylor and there was this guy who bought all his parts from us except for the power supplies because he thought our power supplies were too expensive and and what it was was he he'd returned all the parts after a year and they'd all be dead and you know and then it's like dude bringing the whole build let's check it out and it was some power supply never even heard of it weighed like nothing it was just this flimsy steel housing not even painted no sleeve cables just the cheapest thing you could buy right and I'm like okay well I think this might be the probably goes no no it powers on it's fine everything powers on it's not the power supply and so then I found a guy in the industry who had a load tester and we put it on there and we hooked up an oscilloscope to it and the ripples and me a hundred you know a rollercoaster oh yeah and I was like - yeah see and I was like nobody does this like reviews and stuff so then I'm like how much can i buy this thing for and I bought all the kit and and that was it so yeah so yeah I've always inspired to try and review power supplies but it looks is it time consuming like it would be well is the time consuming part is actually running all the tests yet for X number time I mean if you want to be thorough you want to do like me you know like we do ten tests at Johnny guru.com cold and hot so it's 20 tests total you're going to want to run it for X number of minutes per test so yeah it can be time-consuming okay are you one more question one more than I've actually cuz I got in here guys I want to ask so many questions is I want to get refreshes if we've got there's fun so maybe it's time did last question final question no no no it's if we got say for instance 100 volts it means yeah 100 or so 100 volt from the wall yeah versus 240 NS tray which would be better for a power supply or other thing the 240 did the 240 okay why is that because you know higher voltage lower current or current load less Heat yeah right so yeah so so those parts on the primary side yeah they're all gonna run cooler because they have less current yeah right going through it that's because I've always looked at the house while using so different numbers and yeah really I never started really physically yeah so if you if you actually yeah so if you actually test the same power supply same loads yeah but with 115 input versus say 230 or 240 mm boy you're gonna find that the 230 240 inputs always a lot more efficient so the Australian is better than run belies in Australia yeah well America America is worse because they were the first with the electricity right so they just made a bad decision right from the start and never changed there is a country that runs which goes around to ATS a to a tivo about 280 Japan's 100 that's that's hard yeah that's hard on a power splay it really is and I mean there's some times where you just have a Paris plane you don't even want in Japan yeah yeah that's that's that's why I know those the deltas are pretty good well exactly I mean so like the only way you can sell a power supply in Japan is if it's a really good power supply because they have only a hundred volt mains it's like whose idea was that and it's yeah I didn't change him for a long very archaic country in ways did I live this anyway guys thank you guys for tuning in we had Johnny Carew and he was um it was very good to having you on man so this fun yes I just want to make sure that sorry if we missed the questions guys Johnny's obviously only taken a little bit of time out to do a live stream and thank you so much because I was really when Corsair said i do you want to interview anyone from Corsair i found out yeah yeah I want to interview Johnny girls I just grew up reading those reviews and laughing my ass off while we gotta keep the readers reading so yeah but while I was getting educated and that is the other thing too is we want to make sure that our spies can be really complicated but we want to make it where people could understand it and that's that's just where I learn assess with arian sort of like the respect and love from the community comes so close and man so thanks a lot yeah well for your time dude and yeah guys we'll catch you guys and of course it there's some really dying questions I did tweet out on Twitter yeah did but you don't want masked people following you I don't know what did reach I that you can ask Johnny oh yeah you should respond yeah I mean if you're on a plane where you bought it exactly laying the hotel rooms yeah yes if you got dying questions for Johnny grew shoot him a question on Twitter and thanks for tuning in and we'll catch you guys in another tech video very soon thanks for everyone for tuning in thanks guys bye
